BIOS firmware image of 8 MB labelled DQ77CP, with no file extension given. The name carries only the board name and the capacity, so version and region details are unknown. A dump like this is written to the SPI flash with a hardware programmer when the board fails to post or the firmware is corrupt. A 4 MB sibling also exists, which suggests the firmware is split across two chips or that two sizes circulate. Back up the original chip and match the image size to the chip before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @vinafix_bios. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
